Domain buying bug

I put an auction on a domain, it was supposed to end like in a hour but wen I went to see it, I found that someone outbid me and got the domain how is it possible ?

Sorry to hear about that. Even if it’s one hour left, anyone outbids you will win the auction and own the domain name.

Yeah but I would’ve outbid my turn but time ended before supposed time that’s what I don’t understand
